i have a test pipe on my 00 Si and i want to know is there anyway to get the CEL to stay off without the use of a stimulator

 

Is it a street car, or track car??

If its a street car, PUT YOUR CAT BACK ON!

No reason that the 2-3 HP gain you get by running a testpipe makes it acceptable

I think that's the only solution too. I'm not aware of any other way to eliminate the cel code. (besides the o2 simulator)

 

Dont put ur CAT back on let that baby roar, get the simulator, or leave the damn light on it aint hurting you. Just check it once in a while to make sure it aint somethin else
